- As shown in
FIGS. 1-4 , the present invention provides acoffee maker 100, especially, a brewing device. Thecoffee maker 100 is configured to brew coffee liquid. Without doubt, thecoffee maker 100 of the present invention can also be used to brew mixed drinks, or soak and brew tea. - In the present invention, the
coffee maker 100 comprises ashell body 110, abrewing assembly 120, aslight pressure assembly 140, aheating assembly 130 and afiltering assembly 150. Thebrewing assembly 120, theslight pressure assembly 140 and theheating assembly 130 are all installed in theshell body 110. Thefiltering assembly 150 is installed on thebrewing assembly 120, and theshell body 110 performs functions of supporting and is configured to support thebrewing assembly 120, theslight pressure assembly 140 and theheating assembly 130. Thebrewing assembly 120 is the main assembly to brew the stuff. The stuff to be brewed is coffee powder, tea or mixed drink and so on. After the stuff to be brewed is added into thebrewing assembly 120, the heated water supplied by theheating assembly 130 is mixed with the stuff to be brewed to form mixed solution. The present invention will be specified taking coffee powder as an example of the stuff to be brewed. The coffee powder is mixed with heated water to form coffee liquid. Theheating assembly 130 supplies heated water to thebrewing assembly 120, so that the coffee powder in thebrewing assembly 120 is soaked in the heated water. Theslight pressure assembly 140 exerts slight pressure to the brewing assembly, so as to ensure that the coffee powder in thebrewing assembly 120 can be fully extracted and that the coffee powder is mixed fully with the heated water, thereby obtaining high-quality coffee liquid. Thefiltering assembly 150 filters the coffee liquid, so as to filter out the impure substances and other particles in the coffee liquid and further ensure fine and favorable coffee liquid, thereby meeting demands of high quality life of users. - The
brewing assembly 120 comprises abrewing vessel 121. Thebrewing vessel 121 is installed on theshell body 110. Thebrewing vessel 121 has a hollow accommodation chamber, which accommodates the stuff to be brewed (namely the coffee powder). The accommodation chamber of thebrewing vessel 121 is a thorough chamber. One end of the thorough chamber is sealed by a chamber-top seal 125 of thebrewing vessel 121, and the other end of the thorough chamber is sealed by thefiltering assembly 150. Namely, the chamber-top seal 125 and thefiltering assembly 150 ensure the tightness of the accommodation chamber of thebrewing vessel 121, so that theslight pressure assembly 140 could supply slight pressure to the accommodation chamber. The other end of the thorough chamber, which is connected with thefiltering assembly 150, is a liquid outlet, through which the coffee liquid in thebrewing vessel 121 flows into thefiltering assembly 150. - The
heating assembly 130 is in communication with the accommodation chamber and is configured to thebrewing vessel 121 with heated water, so that the coffee powder in the accommodation chamber can be soaked in the heated water. What's more, according to different demands of tastes, users can choose heated water with different temperature and different coffee soaking time, which is convenient for users to use. Theslight pressure assembly 140 is in communication with the accommodation chamber and is configured to pressure to thebrewing vessel 121, and under slight pressure, the impure substances in the coffee powder are extracted. What's more, the working sequence of theheating assembly 130 and theslight pressure assembly 140 is as follows: firstly, theheating assembly 130 supplies heated water to thebrewing vessel 121 to soak the coffee powder; secondly, theslight pressure assembly 140 supplies slight pressure to thebrewing vessel 121, so that the soaked coffee powder can be fully extracted and that the coffee powder can be completely dissolved in the heated water, thereby obtaining high quality brewed coffee liquid. - The
filtering assembly 150 takes effects of protection and discharge. Thefiltering assembly 150 is installed on the lower part of thebrewing vessel 121. Thefiltering assembly 150 is in communication with the accommodation chamber, so that the coffee liquid in thebrewing vessel 121 can be filtered by thefiltering assembly 150, thereby removing the impure substances and other particles in the coffee liquid and ensuring favorable taste of the coffee liquid. Moreover, the coffee liquid in thebrewing vessel 121 is pressed out by theslight pressure assembly 140 or pumped out by a pump. In this embodiment, the coffee liquid in thebrewing vessel 121 is pressed out by theslight pressure assembly 140. Lower end of thefiltering assembly 150 has aliquid outlet 1511. When the coffee liquid is being brewed, theliquid outlet 1511 is sealed, and theslight pressure assembly 140 supplies pressure to thebrewing vessel 121, so as to extract impure substances in the coffee powder. After the coffee liquid is brewed, theliquid outlet 1511 opens, and theslight pressure assembly 140 continuously supplies pressure to thebrewing vessel 121. Under the slight pressure, the coffee liquid in thebrewing vessel 121 goes through and is filtered by thefiltering assembly 150, and flows out theliquid outlet 1511. Coffee making is convenient and fast, and the brewing speed of coffee liquid is enhanced, which is convenient for users to use. - In principle, the shape of the accommodation chamber is not limited, as long as it can be ensured that the coffee powder can be soaked by the heated water. What's more, according to different usage demands, users can choose different soaking time, so as to ensure appropriate solution of coffee powder and improve extraction effect. The
coffee maker 100 of the present invention achieves intelligent and automatic brewing through exerting air pressure, and extracts impure substances in the coffee powder by supplying slight pressure uniquely, thereby obtain high quality brewed coffee liquid. The extraction effects of the present coffee maker in concentration, temperature, flavor, and taste of the coffee liquid are improved so much that the classical coffee maker and the traditional pressure coffee maker in the prior art can never achieve these effects. - At present, the coffee maker in the prior art usually adopts the following coffee making method: soak the coffee powder primarily with hot water, and then adopt the method of natural dripping to make coffee liquid. This kind of coffee maker has the problems of insufficient dissolution of coffee powder and long time of brewing coffee, which will affect usage. As for the
coffee maker 100 of the present invention, after the coffee powder is added to the accommodation chamber of thebrewing vessel 121, theheating assembly 130 supplies heated water to the accommodation chamber, so that the coffee powder can be mixed with the heated water fully; theslight pressure assembly 140 supplies pressure to the accommodation chamber; under slight pressure, impure substances in the coffee powder are extracted, so that the coffee powder can be dissolved in the heated water fully, thereby obtaining high quality brewed coffee liquid, and achieving improvement in concentration, temperature, flavor, and taste of the coffee liquid. The efficiency of brewing coffee is enhanced, and the coffee maker is convenient for use. Thecoffee maker 100 of the present invention has a simple structure, has low cost and can relief the burden on the users. What's more, thecoffee maker 100 of the present invention has a simple structure, is convenient for users to use and saves time. - The
coffee maker 100 further comprises acontrol assembly 160. Thecontrol assembly 160 comprises acontrol panel 161 and acontrol board 162. Thecontrol panel 161 is disposed on theshell body 110. Thecontrol board 162 is disposed in theshell body 110. Thecontrol board 162 is electrically connected with thecontrol panel 161; thecontrol board 162 is electrically connected with thebrewing assembly 120; thecontrol board 162 is electrically connected with theheating assembly 130; thecontrol board 162 is electrically connected with theslight pressure assembly 140. Through thecontrol assembly 160, thecoffee maker 100 achieves intelligent control, thereby speeding up the intelligent process of the coffee maker and making convenience for users. Many kinds of touch keys, such as the heating temperature of theheating assembly 130, the soaking time of coffee powder, the pressure exerted by thebooster pump 141 and so on, are provided on thecontrol panel 161, and the users can make a choice according to their own demands. The coffee maker of the present invention can meet different demands of the users, and it is convenient for users to use. Control programs are stored in thecontrol board 162 and control theheating assembly 130, thebrewing assembly 120 and theslight pressure assembly 140 to operate. - In one of the embodiments, the
slight pressure assembly 140 comprises abooster pump 141 and apressure pipe 142. Thebooster pump 141 is connected with thepressure pipe 142. Thepressure pipe 142 is in communication with the accommodation chamber. Through thepressure pipe 142, the slight pressure is transferred to the accommodation chamber of thebrewing vessel 121 by thebooster pump 141, thereby thecoffee maker 100 realizes brewing coffee under slight pressure. Thebooster pump 141 is installed inside theshell body 110. Thepressure pipe 142 goes through theshell body 110 and is connected to thebrewing vessel 121. Thepressure pipe 142 is in communication with the accommodation chamber through the top or the side wall of thebrewing vessel 121. It should be specified that, when thepressure pipe 142 is in communication with the accommodation chamber through the side wall of thebrewing vessel 121, the opening of thepressure pipe 142, which is disposed in the accommodation chamber, is configured to be lower than the liquid height of the coffee liquid in the accommodation chamber. So that, when thebooster pump 141 supplies slight pressure to accommodation chamber, air bubbles are produced inside the coffee liquid. The air bubbles rise and burst, and have effects of stirring and mixing the coffee powder, so that the coffee powder could be mixed with the heated water fully, thereby increasing the concentration of coffee in the coffee liquid and increasing the extraction rate of the coffee powder, improving the flavor of the coffee liquid, etc. - Further, the pressure supplied by the
booster pump 141 to the accommodation chamber is less than 0.4 MPa. Namely, thebooster pump 141 only supplies slight pressure to the accommodation chamber of thebrewing vessel 121, and the pressure less than 0.4 MPa supplied by thebooster pump 141 can meet the requirements of extracting impure substances from the coffee powder, and can ensure that the coffee powder can be fully dissolved in the heated water and filtered out by thefiltering assembly 150. What's more, when the pressure supplied by thebooster pump 141 is larger, the requirements for the seal of thebrewing vessel 121 and the quality requirements for thebooster pump 141 will be higher, which will increase the product cost of thecoffee maker 100 and be not convenient for users to use. Therefore, the pressure less than 0.4 MPa supplied by thefore pump 141 can meet the requirements of extraction of the coffee powder and ensure safe operation of thecoffee maker 100, so as to avoid occurrence of safety accidents. Preferably, in this embodiment, the range of the pressure supplied by thebooster pump 141 to the accommodation chamber is from 0.15 MPa to 0.25 MPa. - The
coffee maker 100 of the present invention brews coffee liquid under light pressure. In brewing the coffee liquid mixed by heated water and coffee powder in the accommodation chamber of thebrewing vessel 121, theslight pressure assembly 140 supplies slight air pressure to the coffee powder in the accommodation chamber, so as to extract the impure substances in the coffee powder and make the coffee powder be fully dissolved in the heated water, thereby enhancing the quality of the brewed coffee liquid, then press the coffee liquid out from thefiltering assembly 150 under the slight air pressure. - In one of the embodiments, the
brewing vessel 121 is further provided with apowder inlet 1211, awater inlet 1212 and anair outlet 1213. Thepowder inlet 1211, thewater inlet 1212 and theair outlet 1213 are all in communication with the accommodation chamber. The coffee powder is input into the accommodation chamber of thebrewing vessel 121 through thepowder inlet 1211. Thewater inlet 1212 is in communication with theheating assembly 130, and the heated water is delivered into the accommodation chamber by theheating assembly 130 through thewater inlet 1212, so as to soak the coffee powder in thebrewing vessel 121. Additionally, as the accommodation chamber is sealed, in order to prevent the heated water from not being delivered into the accommodation chamber, thebrewing vessel 121 is provided with theair outlet 1213, which is in communication with the accommodation chamber. When the heated water is added into the accommodation chamber from theheating assembly 130, the heated water enters into the accommodation chamber through thewater inlet 1212, and simultaneously, the air in the accommodation chamber is discharged from the accommodation chamber through theair outlet 1213, so as to keep a balance of pressure in the accommodation chamber. - In one of the embodiments, the
brewing assembly 120 further comprises adriving unit 122, atransmission mechanism 123 and a chamber-top seal 125. The drivingunit 122 is connected with thetransmission mechanism 123.
